commit df18f71b565c29f6f1ebd385cb1aed97d00e9660
Author: David Guillen Fandos <david@davidgf.net>
Date:   Thu Jun 15 04:45:03 2023 +0100

    Add MIPS Allegrex CPU as a MIPS2-based CPU
    
    The Allegrex CPU was created by Sony Interactive Entertainment to power
    their portable console, the PlayStation Portable.
    The pspdev organization maintains all sorts of tools to create software
    for said device including documentation.
